Detailed explanation-1: -The correct answer is they are seedless plants. A spermatophyte, also known as phanerogam is any plant that produces seeds. They are a subset of the embryophytes or land plants. It is classified into two parts: Gymnosperms and Angiosperms.

Detailed explanation-2: -So, roots and seeds are not the characteristic features of angiosperms.

Detailed explanation-3: -Angiosperms do not produce cones and produce flowers/fruits instead. Gymnosperms are vascular plants that produce cones. Cones have their seeds exposed on the surface of their leaf-like structures instead of the seeds being enclosed in an ovary.

Detailed explanation-4: -Angiosperms are the only plants that have concealed seeds. The seeds in angiosperms are found inside the fruit. The fruit protects the seed and also gives nutrition. No other division in the plant kingdom bears fruits.

Detailed explanation-5: -Angiosperms. Angiosperms produce flowers, which are special structures for reproduction. They contain male parts that make pollen and female parts that contain ovules.
